Oh and 1 more little problem, according to the manual I have the SMBus disabled (comes that way by default, I did not touch the jumpers and I double-checked that they were in the DISable position). But in windows, it still detects the SMBus and installed the drivers for it. Not a big deal except it uses an IRQ...

Are the SMBus jumpers labelled backwards (and wrong in the manual)? Is there errata on this?

Alright payday's on Thursday...so which brand do I buy? I'm getting 2 sticks of 512 MB PC3200 RAM. Do I go with Corsair, Kingston, or Mushkin? Mushkin links don't work, so here are the other two I'm looking at: Corsair and Kingston.

Advise!

Just so you know that ram is cheaper the Corsair at outpost.com I have this memory coming to go with my Asus P4C800-E and 2.8C.

Yes I did just save you 40 bucks (unless you dont have to pay sales tax) you can thank me later. :beer:

Running the lastest releast Bios 1010 and I'm having the samem problem as back with 1004.
setting the PAT to Turbo causes my system to not boot.
I have the Performence Mode enabled for the Memory as well, disabling it doesnt help.
Memory is set to spd, its Kingston ValuRam PC3200 and run in 400Mhz Dual linear mode or what not.

any programs someone can recommend that extract what the memory timings are, etc.

arg i just want everything to work

CPU_Z will give you the speed and timings.

 

[egale]

The performance settings in the bios are particularly unstable for most people. They should be disabled or set to auto if possible. Also, do not use SPD. Set everything manually as Asus does not use the correct SPD settings from the chips. If you know the advertised timings of the memory you bought, try entering those. Remember though that ASUS changes the order of the memory settings so what the world states as 2-x-y-6, the order they are listed in the bios are 2-y-x-6. Set the vdimm to 2.75 and disable usb legacy support.

At 400(1:1) with 208fsb(2912Mhz) your mem is running DDR416 but with 320(5:4) with 225fsb(3150Mhz) your mem is only running DDR360. That is why most ppl use a 2.6C to get the lower multipier. My 2.6C setup runs 320(5:4) with 261fsb(3393Mhz) DDR418 @ 2-2-2-5 (Kingston HyperX3500 CL2). My 2.8C setup runs 400(1:1) with 236fsb(3304Mhz) DDR472 @ 2.5-3-3-7 (TwinMos PC3700 CL2.5). The 2.6C system is faster than the 2.8C system.

Got a question for you jhites have you tried the 2.8 C at the 5:4 with higher fsb, I see you run it at the 400 1:1.

I was told at 5:4 250 fsb the ram would be at ddr400 so it would be async with the fsb, the reason I ask this is cause I have the Asus P4C800-E coming but I am getting Corsair 3200 not 3500 and wanted to see what you got out of yours.

At 5:4 you should be able to get even more fsb out of it and run the memory faster then 400 and be stable wouldnt you?

You are correct that the mem would be running async at 250fsb 5:4. The memory in my 2.8C system is running sync at fsb 236 = DDR472 not 400. Yes, I did test it running higher fsb using the 5:4 divider. The chip topped out at 247fsb (3457Mhz) which put the ram at DDR395. Total overall performance was better running it 236 sync than it was running 247 async.

If I enable the "Turbo" mode I get a corrupted bios! I don't think it works right on this board.

I tried to overclock mine but don't get very far without memtest86 errors. At the stock voltages, about 206 seems to be the limit (2.8c = 2884mhz, memory at 400) for a whopping 3% overclock, I just don't think it's worth it, I put it back to stock speed. I tried playing with the voltages but that seemed to make things worse. My 2.8c Vcore runs at 1.55V, if I raise it to 1.6 or 1.7 it crashes harder

 

[walk2]

*Oh I forgot.

When I first started overclocking it I got it up to 210 I think, maybe a bit higher, and it would run memtest for about 3 minutes (I stopped it after that) but I had left the memory speed on "auto" and memtest was reporting speeds in the 1500 range (instead of 2000+) so I guess the board was automatically throttling down the ram? I didn't test it much at that speed, I may go back and try it. Do you think it would be faster at 200/400 2800mhz or 210/320 2940mhz?

 

[egale]

You need to raise vdimm to 2.75 and turn off usb legacy devices.

 

[trininox]

I knew about the usb legacy, thx for the tip about the vdim to 2.75, but i figured that since they took the Turbo out of past bios it wasnt really working properly, then i saw it back in i thought maybe it would be workin now, guess not... I wish it did since the test copies reviewers that i've read had it worked for them and they saw the 3-5% increase in performence that is supposed to get without any overclocking... i've found the turbo only worked when i overclock it about 15% if remember correctly.

I probably am stupid but I didnt apply the thermal paste to my heatsink/proc because i wasnt sure if my heatsink had a "heatpad" but i assume that after seeing my frient get a lower spd proc with a not so nice retail heatsink it had a black pad, i guess because it was all aluminum and no copper over the core like mine... another friend also had to replace his proc after testing it in a friends machine beacuse it toasted. the retail heatsink for our same proc's has changed (we got the 3cGhz when it first came out) now his replace ment has a different style heatsink.. instead of a plus sign configuration with a quarter size copper dick over the core of the cpu chip it is straight parallel aluminum fins with a copper block covering the the whole chip, so blah blah

I prolly should apply the thermal paste to help keep the temps down under loads?
should i perhaps claim my proc is broke and get this new design, or do they change heatsink designs as much as most people change their shirt?

I could always go for an aftermarket cooler but i dont plan on doing any overclocking for some time.

 

[walk2]

Right now I have it working great at 200/400 C2-3-3-6 and that's likely where I will leave it.

If I go over 206 I get corrupted BIOS.
If I set RAM to SPD I can go as high as 209 before memtest errors/reboots. I've tried Vdimm 2.75 and Vcore 1.8 (cpu is 1.5 stock) no dice.

If I set RAM to 320 it will post up to about 215 but memtest reboots immediately at 10-12% on the first test. Sucks hu..

The thermal compound is used to fill the microscopic gaps of the sink and processor. Even if you lap both you should always use a thermal compound. Very, very thin layer. You may get a better OC after applying the paste due to better temps.

It's most likely your memory and not the 2.8C that is holding you back on your OC. I am running my 2.8C @ 236fsb(1.575v) with PC3700 TwinMos using 1:1 ratio. There have been many reports that these chips actually run more stable and can keep a higher OC using less vcore. Keep the vcore @ 1.60-1.65v or less. Anything over that would be useless without super cooling.

Hello everyone,

With my P4C800-E and 1GB Corsair 3200LL TWINX, I have only gotten my timings down to 2-3-2-5-8.
Regardless of RAM voltage, 2-2-2-5-8or4 will not boot.
I also tried the settings that jhites used with his Kingston 3500 RAM, but nada.

I can get an OC of 3.384 FSB 260 with the 2-3-2-5-8 timings that gives me a RAM Freq of 208.
At boot it says 3.4Ghz, but CPUZ says it's 3.384.
I am not sure of it's stability though.

Memtest at 2-3-2-6-4 showed no errors.
I haven't tested 2-3-2-5-8 yet.

Two questions:
What do you think of my results?
I'm mostly interested in getting 2-2-2-5-4or8, so is there anything else I should try?

Using the Corsair LL, I would say that those are very good results. Many ppl have and are having very difficult times with that ram on i875/i865 boards. Since you have passed memtest, run two instances of Prime95 to verify stability. Be sure and use the most recent version. You will need to start the 2nd instance from the command line like this with the -a2 switch.

ie: D:\Program Files\Prime95\Prime95.exe" -a2

Memtest at 2-3-2-6-4 showed no errors.
I haven't tested 2-3-2-5-8 yet.

Check with memtest in the upper left corner for Mb/s on each of the two timings to see which one is giving higher speed.

What vcore,vagp and vdimm are you using and what cooling?

 

[fvlmasl2]

I have searched for an answer but can't seem to find one....I have a p4c800 dlx, when i come out of standby i have to reboot in order to get my email and internet to work again. I have 3 pc's connected with a Linksys router. Two of the pc's are ASUS boards and 1 MSI. The problem occurs with both the ASUS and not the MSI.

Greetings all:

I have a ASUS P4C800-E Deluxe Motherboard and it seems like with my memory at 1:1 ratio (400 on the ASUS), and Performance Acceleration Mode set to Enabled, the FSB at 200 will show PAT Enabled under the Memory tab in CPU-Z 1.19 and SiSoft Sandra MAX. However, at 230-233FSB, it will show PAT as disabled, is this the way it's supposed to work because I have it enabled in the BIOS. This is a P4C-3.2Ghz CPU at stock voltages. The RAM is 4 sticks of matched Hynix PC3200 DDR400 512MB CL3 running at 3-3-3-8-8 at stock voltages which came from a Dell Dimension XPS.

 

[senior guy]

At this point in time, what is the best performing (stable) BIOS version to use with the P4C800 Dlx?

 

[HigherGround]

so is the non Deluxe version of this board available in the US? it's listed over @ asus' site.

 

[jamesbond007]

I'm currently running a P4 3.0C GHz w/HT enabled on the P4C800-E Deluxe, BIOS 1011 beta 2, 4x512MB PC3200 Crucial DDR. No overclocking, just TURBO enabled in the BIOS. It's like a rock.

Just one quirk that I have found...when I run the Audigy 2 Platinum update via the web, it cannot detect my card...nor can I manually install the latest drivers as the install hardlocks the computer. I've tried different PCI slots, but no avail.

Anyone had an experience like this with the board? I've tried disabling/enabling HT in the BIOS to see if that would alleviate any SMP issues with the drivers, but no luck. However, the drivers off my CD installed fine and everything but the actual drivers updated fine when I did the manual install.

Just a update, it seems that with PAT, at 233FSB, with one set of dual channel 512MB Memory, the PAT is enabled and the memory bandwidth benchmark in SiSoft Sandra MAX works but when I place both sets (all 4) of the same batch memory, PAT is disabled and then SiSoft Sandra MAX's memory bandwidth benchmark just flashes through the part where it usually does the test and shows 0MB/sec bandwidth. Does PAT work only on one set of RAM and not two sets?

 

[trininox]

What are some temps poeple have under normal and load situation?

Looking at the recorded history in Asus Pc Probe

Normal CPU is mid-30's (95F)
Load CPU is mid-50's Never higher than 60 Cel. (130-140F)

Normal and Load MB is low 30's all the time. (80F)

I've only seen it go to 60/140 on my proc when just recently running Prime95 on my machine

 

[jhites]

26*C = Ambiant Room temp
34*C = Full Load MB
49*C = Full Load CPU (Spikes to 51*C)
